This forest plot visualizes the associations of participants’ features (N = 241) with a sexual exposure groups, analyzed using ordinal logistic regression models, and b the HIV-1 infection status outcome, analyzed using logistic regression models. The X-axis denotes the odds ratio (OR), while the Y-axis lists the various demographic and clinical characteristics. Each feature’s effect size (OR) is symbolized by a diamond. An accompanying horizontal line represents the 95% confidence interval (CI), indicating the range in which the actual effect size is likely to reside. A vertical red line at the OR of 1.0 serves as a reference for no effect. For each feature, the exact OR, 95% CI, and the p-value (two-sided)—derived from logistic regression models—are presented in an adjacent table.
